Application filed August 2,1911. Serial No. 642,031.

To all whom it may concern:

Be it known that I, Hyman ELI GOLD- enno, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have. invented certain new and .space movements. .Mountedupon'said bar is a totalizer, which totalizer can be adjusted upon thebar so as'to be in anyone of a number of positions, which positions areusually one-tenth of an inch apart. This is accomplished in the abovepatent Dy-pro 'viding the bar with a rack having a series of spaces cuttherein one-tenth of an inch apart, and by providing the totalizer witha latch capable of being inserted into any one of said spaces to therebylock the total;

izer in the desired position upon said bar.

In a great many cases it is superfluous to havethe possible lockingpoints of the totalizerf upon the bar in such number as shown intheabove cited patent.- It is very often desirable to be able'to locatethe totalizer in very few locations only, in which case the multiplicityof locking spaces provided in the construction of the above mentionedpatentiis an annoyance, as the operator has to be quite careful in whichspace the latch of the-tot-alizer is inserted. To avoid this annoyingconstruction is one of the main objects of my invention. 1

This invention is illustrated by one sheet of drawings, in which,]

Figure 1 represents the totalizer holding bar; and Fig. 2 represents alocking plate, both in isometric perspective.

The bar is composed of the main body 1, usually made of cast-iron orsimilar material, and is provided at its ends with holes 2-2, which.serve for the insertion of screws, by means of which it is fastened tothe car riage of the typewriter, as illustrated in the cited patent. Itis provided on its lower edge with a rack 3, which has therein a seriesof spaces 4 and teeth 5, which teeth and spaces serve to locate the barin the proper Specification of Letters Patent.

position during the operation of the calculating machine, as isthoroughly described in the cited patent. fact that these spaces 4 arenot the ones which serve to lock the totalizer to saidbar.

Attention is drawn to the' i The bar is also provided with screws 6,

whereby plates 7, 8, 9, 10 and 11 are fastened to the upper portionthereof, and these plates are the means which serve to locate thetotalizer in reference to said bar. Each of these plates is providedwith one or more spaces 12 cut therein. These spaces '12 serve for thereception of the totalizer latch, as previously mentioned. Uponexamination of the drawing, it will be seen that the plates 7 8, 9, 10and 11 are not identical in shape, the location of. the space 12 in eachof said plates being different. These plates are supposed to be ofstandard length, and

each of them is pierced with two holes 13 for the reception of thescrews 6, whereby these plates are fastened to the bar 1. The positionof the space 12 in the plate 8 is onetenth of an inch (or one carriagetypewriter step) removed from the position of said space in plate 7.Similarly for plates 9, 10 and 11. It will thus be seen that by means ofa sufiicient number of plates, which are kept in stock, any desirableadjustment of spaces 12 relative to each other can be brought about,particularly as in ordinary commercial work it is very seldom necessaryto have the locking spaces 12 very close together;

- In operation, it the to-talizer, is located on thebar that is latchedby any one of the spaces, and it is desired to move the tot-alizer tothe next adjacent space, it is necessary and quite sufficient to removethe totalizer latch from its space and to slide the totalizer until itslatch will-Snap into the next space. This, as above explained, could notbe accomplished with the form of locking bar shown in the cited patent.

, It will be seen that in the plates 7, S, 9, 10 and 11, the spaces areat diderent distances from the ends of the plates. This requires quite anumber of the plates in order to be sufficient for all possiblerequirements, but

each plate can be fastened to the bar 1 in' two positions, namely in theposition illustrated in Fig. 1, and also fastened in another manner,namely by turning the plate end for end, and thus bringing the notch thesame distance from the right end of the plate that it Was'previouslyfrom the leftend thereof. The total number of plates required is thushalved. It is also possible to again halve this alreadyhalved number ofplates by constructing each plate as shown in Fig. 2, which shows amodification. Each plate is here provided with two spaces cut therein,which spaces are non-symmetrically located in reference to the ends ofsaid plate. This plate can therefore be fastened to the bar 1 in fourdistinct positions, thus bringing its locking space in four distinctoperating )ositi ons. struction, the number of varieties of platesbecomes comparatively limited and well within commercial requirements.

I claim:

1; In a calculating-machine totalizerholding bar, the combination of thebar, and

Because of this cona space for the reception of the totalizer latch, andmeans for fasteningsaid holding plate to said bar in either of two ormore positions to thereby change the relative location of said holdingspace in reference to said bar.

3. In a calculating -1nachine totalizerholding-bar, a holding plateprovided with two or more spaces therein for the reception of thetotalizer latch, and means for fastening said plate to said bar in aplurality of positions to thereby locate said holding space on said barin a corresponding plurality of positions.

4 In a calculating-machine 'totalizerholding-bar; a holding plateprovided with two spaces therein for the reception of the totalizerlatch, and means for fastening said plate to said bar in any of fourpositions, to thereby locate said holding space on said bar, in any ofsaid four corresponding positions.
